Online engagement also helped the campaign raise a huge war chest of funds that outstripped the Republican campaign budget. The BB03 reports that Obama's internet fund-raising activity attracted more than three million donors and raised 'about $650m (£403m) - more than both presidential contenders in 2004 combined' . This meant that Obama had the resources to maintain more campaign offices in more locations than the Republican camp and could also buy more broadcast media airtime than his opponent, enabling his campaign to reach more voters than the Republicans.
